The government of Tanzania is urging fishermen to stop hunting dolphins, a report in the Daily News says.

The report says dolphin hunting has become common practice in the Dar es Salaam and Tanga regions. It’s often done by “dynamite fishing,” in which explosives are chucked into the water to kill all marine life in a large area. Dolphin meat is used to bait sharks, which is what the fishermen are really after. Shark fins are a delicacy that sell for high prices.

Tourists have even spotted fishermen catching dolphins in Tanga Coelacanth Marine Park. Tourism is big business in Tanzania thanks to its diverse wildlife and being home to the Mt. Kilimanjaro part of the Serengeti. Seeing Flipper being blown up, hauled into a boat, cut to pieces and used as shark bait would definitely ruin an ecotourist’s vacation.

Dolphins have been a protected species in Tanzania since 2009. It’s not clear how well this is known among fishermen, however. Even if fishermen do know they’re flaunting the law, the need to be breadwinners for their families may outweigh any concerns about conservation or the health of an industry of which they are not a part.

Passengers aboard a whale watching tour off the coast of California got a rare treat recently when they witnessed a large dolphin stampede. The tour was being conducted off of Southern Cal’s Dana Point by a company called Dolphin Safari when they came across a large pod of the creatures swimming near the surface. The result was a spectacular show of wildlife churning through the water that has to be seen to be believed.

Fortunately, someone aboard the ship had a video camera on hand and captured some footage from the phenomenon. The video was posted on YouTube a few days back and has already been viewed over 400,000 times. It features more than 1000 dolphins swimming along at high speed as they “stampede” out into the ocean. There is even footage that was taken from one of the boat’s underwater viewing pods, giving viewers an excellent look at the action.

Mark Peters recently went fishing for tuna off the coast of Santa Cruz in California. He took with him his trusty GoPro video camera and a newly built “torpedo” housing that would allow him to film underwater. Peters hoped to capture some great footage of their catch of the day but instead wound up with some of the most amazing video of dolphins that you could ever hope to see. The images are so good in fact, you’ll swear they were created by Pixar.

The video, which you’ll find below, just serves to underscore how excellent and versatile the GoPro cameras really are. They were designed for use in action sports, such as mountain biking or kayaking, but have evolved into a fantastic device for capturing video in a variety of situations. The footage captured here simply has to be seen to be believed.

In a landmark move, Whole Foods has just announced that starting on April 22 — Earth Day — it will no longer sell seafood from depleted or otherwise unsustainable fisheries, or species harvested with ecologically damaging methods such as trawling. The industry ratings for these species are determined by the Blue Ocean Institute and California’s Monterey Bay Aquarium, which produces a popular “Seafood Watch Recommendations” pocket guide and phone app for shoppers. Say bye-bye to Atlantic halibut, skate, octopus and sole.

It’s a bold move for the world’s largest, most powerful green grocery chain to defer customer demand for better buying practices, but according to Whole Foods’ seafood quality standards coordinator Carrie Brownstein via an AP article, “In the long term, what we’re really looking to do is help reverse trends of overfishing and by-catch, so that really we can move the industry as a whole toward greater sustainability.”

So how does what you eat here at home have a global impact? Depletion of any fishery always has a negative effect on the food chain because of a ripple effect. Foreign fisheries may also employ unsound fishing methods that increase by-catch (think dolphins and other aquatic species, albatross, etc.). You may love Chilean sea bass (it’s actually Patagonian toothfish) but it has long been a fishery on the verge of collapse and by purchasing it at the store or ordering it at a restaurant, you create demand for that product. Once a species is extinct, it can seriously throw a marine ecosystem out of whack. Plus, you know, extinction kind of sucks.

It’s harder for world travelers to be on top of what’s sustainable and what’s not, especially if, like me, you love street food. In developing nations, especially countries with a coastline, fishing is usually a key part of the local economy. But saving our rapidly depleting oceans trumps putting a few pennies in local pockets: they’re not looking at the big picture, which is the more seafood we consume, the less there is to sell.

Order something besides seafood unless you’re positive it’s caught in a non-environmentally degrading way, from a healthy fishery. Go to the Monterey Bay Aquarium’s Seafood Watch Recommendations site for a global guide to what’s sustainable and what’s not. It offers alternatives, so odds are, you can travel and have your lobster dinner, too.

While researching my travel series on Greece I noticed some interesting things that didn’t fit into any of the articles. Some of these observations may be obvious to those more familiar with Greece, but odd first impressions are one of the fun things about travel!

1. Flying low over the Aegean as we made our descent into Athens airport, I swear I saw dolphins playing in the blue waters. We were still high enough that they were only visible as dots, but there was a whole group of these dots appearing and reappearing in the water, as if they were coming up and diving. Has anyone else seen this?

2. Like many countries, Greece has a smoking ban in public buildings. It’s often ignored, especially in bars and cafes. Some places even have ash trays on the tables.

3. I always like hearing the local music, in my hotel I tuned into MAD TV, a music video station. I discovered lots of Greek stars I’d never heard of (is DEMY hot or what!?) and noticed a strange thing–cans of Red Bull appear in almost all their music videos. Even the lovely DEMY knocks one back in her latest video. Did Red Bull buy up Greek music or just MAD TV?

4. Greece is very visitor-friendly by having bilingual signs in all the touristy areas. This is a bit of a trap, however, because as soon as you get used to them and go someplace a bit out of the way, you’ll be staring at Greek-only signs.

5. Have no fear, you can always learn the Greek alphabet. Many of the letters are the same as our alphabet and you’re already familiar with some of the others. Learning the Greek alphabet takes less than an hour and you’ll discover so many words that are the same or close enough to English that the hour will be well spent.

6. Greek can still throw you some curve balls. For a while I thought “ne” meant “no” since it’s similar to so many other “no” words (nein, nyet, non). In fact it means yes.

7. Athens has a large and active Couchsurfing community. Get in touch before you go and they’ll show you some awesome nightlife!

8. Small Orthodox Christian shrines can be found everywhere. Some are the size of a mailbox with only room enough for a little icon and a candle. These are often found beside roads. Others are little buildings that can fit a dozen or so people. They’re tucked away wherever there’s room. Dealerships for these these ready-made churches look like mobile home lots.

9. I saw a lot of graffiti, especially in the smaller towns, that was actually advertising for local businesses. I’m not sure if the businesses themselves are tagging concrete bridges and blank walls or if it’s their loyal customers, but I suppose it’s a cheap way to advertise during times of financial cutbacks.

10. Speaking of graffiti, my neighborhood in Madrid is covered with the tag “farlopa”, which is slang for cocaine in Spanish. Walking through the Exarchia neighborhood in Athens one night I saw the “farlopa” tag. Same word, same style. I guess the tagger went on a road trip!
